Step 4. Contact check calibration
1. Short the Series 2600 sense low and output low terminals, as shown in
. Also short the sense high and output high terminals together, as
shown in the figure.
2. Allow the readings to settle, then get the Series 2600 readings:
r0_hi, r0_lo = smua.contact.r()
3. Connect a 50
Ω
resistor between the sense low and output low terminals, as
shown in
. Also connect a second 50
Ω
resistor between the
sense high and output high terminals as shown in the figure.
4. Allow the readings to settle, then get the Series 2600 readings:
r50_hi, r50_lo = smua.contact.r()
5. Send the contact check low calibration command:
smua.contact.calibratelo(r0_lo,
Z_actual,r50_lo,50_ohm_actual)
Where:
r0_lo
= Series 2600 0
Ω
low measurement
Z_actual
= actual zero value
r50_lo
= Series 2600 50
Ω
low measurement
50_ohm_actual
= actual 50
Ω
resistor value
Typical values:
smua.contact.calibratelo(r0_lo,0,r50_lo,50.15)
(Where
r0_lo
and
r50_lo
are measurements taken in steps 2 and 4
above.)
6. Send the contact check high calibration command:
smua.contact.calibratehi(r0_hi,
Z_actual,r50_hi,50_ohm_actual)
Where:
r0_hi
= Series 2600 0
Ω
high measurement
Z_actual
= actual zero value
r50_hi
= Series 2600 50
Ω
high measurement
50_ohm_actual
= actual 50
Ω
resistor value
Typical values:
smua.contact.calibratehi(r0_hi,0,r50_hi,50.15)
(Where
r0_hi
and
r50_hi
are measurements taken in steps 2 and 4
above.)
